“My greetings to all Swayamsevaks as the RSS completes 90 years in service of the nation,” Modi said in a tweet.

The RSS, Bharatiya Janata Party’s ideological parent, was founded on Vijaya Dashami on 27 September 1925 as a social organisation to provide character training through Hindu discipline and to unite the Hindu community.

It describes itself as a cultural outfit devoted to upholding Hindu values.
